Instead of focus its engineering might on a revolutionary design, Motorola opted instead for bettering battery life. Hence, we have the Droid RAZR Maxx HD. Labeled the "Energizer Bunny of all smartphones," the Verizon exclusive carries the largest battery ever stuffed into a mobile phone: a 3,300mAh cell capable of powering a handset over an entire day on moderate/heavy use. The 4.7-inch Super AMOLED HD display might play second fiddle on the spec sheet, but it produces amazing viewing angles and sharp resolution.
